Making Checkbox complete a function? HELP

Question

First and foremost, forgive me if I do not explain this in technically correct fashion. I have enough knowledge to understand, but not enough to be dangerous. In other words, I probably have no clue what I am talking about!
I am working with Adobe Xi Pro. I have a form that I have four fields. 1. CostVehicle 2. Trade 3. Rebate 4. TaxValue
I have discovered how to calculate the TaxValue box to where CostVehicle-Trade-Rebate will give me the Taxable Value
However, I want to add a checkbox behind the Taxable Value. The scenario I would like to happen is as follows:
If the check box is selected noting an AOD (act of donation) then the TaxValue field will either equal 0.00 or state AOD but when the checkbox is NOT checked then I would like my calculation to remain the same from CostVehicle-Trade-Rebate
Is this possible? I have done some searching and feel like a javascript would be what I need to write to make this function to happen. However, again I am not sure whether to javascript or not to javascript?!
Any information would help!
Many thanks,
Angela

Hello David,
You can definitely achieve this using F4IF_INT_TABLE_VALUE_REQUEST & you have to pass MULTIPLE_CHOICE = 'X'.
This will allow the user to select multiple values from the hit list.
TABLES spfli.
SELECT-OPTIONS: s_carrid FOR spfli-carrid NO INTERVALS.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_carrid-low.
  TYPES: BEGIN OF ty_line,
           carrid   TYPE spfli-carrid,
           carrname TYPE scarr-carrname,
         END OF ty_line.
  DATA: it_list TYPE STANDARD TABLE OF ty_line,
        w_return_tab TYPE DDSHRETVAL,
        i_return_tab TYPE STANDARD TABLE OF DDSHRETVAL,
        v_repid TYPE sy-repid,
        v_dynnr TYPE sy-dynnr.
  v_repid = sy-repid.
  v_dynnr = sy-dynnr.
  SELECT carrid carrname
              FROM scarr
              INTO TABLE it_list.
  IF sy-subrc = 0.
    CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
      EXPORTING
        retfield        = 'CARRID'
        dynpprog        = v_repid
        dynpnr          = v_dynnr
        dynprofield     = 'S_CARRID-LOW'
        value_org       = 'S'
        multiple_choice = 'X'
      TABLES
        value_tab       = it_list
        return_tab      = i_return_tab
      EXCEPTIONS
        parameter_error = 1
        no_values_found = 2
        OTHERS          = 3.
    IF sy-subrc = 0.
      s_carrid-sign = 'I'.
      s_carrid-option = 'EQ'.
      LOOP AT i_return_tab INTO w_return_tab.
        s_carrid-low = w_return_tab-FIELDVAL.
        APPEND s_carrid.
      ENDLOOP.
    ENDIF.
  ENDIF.
